Tracing paper is sold in any paper shop. As you know, I'm also from
europe (Switzerland) and as said, every shop should have it. I haven't
found big differences among them. Maybe it's worth a try? Note thouhg
that due to the not so 100% transparency nature of tracing paper
exposure time may have to be increased a little.

Yep, such things often become a problem

>so i have to experiment myself...

Well, at lest somtimes it's fun - somtimes it get's harder. I figure
it depends on the amount of time available.
